The Peak Family tools include a leak detection tool that can probe for leaks in your wellbore. To test for leaks, the tool is deployed to target depth. At the target depth, the J-index is activated, enabling the tool to land off within the tubing. Spang jars are used to gently jar down. This initiates closure of equalization ports, followed by expansion of the seal element. Once set, a pressure test is applied from above. If the pressure test fails, it indicates a leak in the tubing wall above the seal. The tool can be reset at a different depth by picking up on the wire to open the equalization ports. After equalization occurs, you can increase the overpull and jar up to collapse the seal element. Next, the leak detection tool is moved to a different depth. Once the tool is reset above the leak location, a pressure test will be successful. The leak detection tool can be reset multiple times without having to pull out of hole. This indefinite-setting capability reduces NPT by minimizing wireline runs. Once testing is complete, the tool is retrieved to the surface. With the results, well integrity can be assessed, and action taken where required to restore well integrity.
